PINION-HOUSING.

SPECIFICATION forming part of Letters Patent No. 679,971, dated August6, 1901. Application l'ed March 16, 1901. Serial No. 51,550. (No model.)

in which-"- allelisin in this specification.

Figure 1 is an end elevation of my improved pinion-housing, partly invertical section. Fig. 1a is a perspective view of a portion of thebearing and the adjacent housing. Fig. 2 shows the same partly in sideelevation and partly in vertical section, the section-plane being on theline II II of Fig. 1. Fig. 3 shows in side elevation a modifiedconstruction of the housing.

My improved housing is made in sections, divided in planes which passthrough or are substantially parallel with the axes of the pinions,- thesections being intertted and held by through-bolts.

In Fig. 1, 2, 3, and 4 are the sections of the pinion-housing. The lowersection 4 is held to the foundation by bolts 5. The section 3 is placedupon it, and the section 2 is superposed upon the section 3,through-bolts 6 bcing employed to draw the sections together. Thedividing-lines between the sections, as

shown in the drawings, coincide with the axes of the pinions 7 7; butthey may be parallel and not coincident therewith. In either case theyare substantially in parallelism with the axes in the sensein which Iuse the Word par- 'Ihe bearings 8 of these pinions are held between theadjacent sections and are formed with angular or projecting portions 9,which engage with the sections and prevent turning of the bearings. Theyare also formed with projections or collars 10, which interlock with thesections of the housings and, with the portions 9, prevent motion of thebearings in said sections and of the sections -relatively to each other.

The sections are hollow, and when assembled they form a case in whichthe pinions are inclosed. The pinions can therefore be oiled bysupplying a body of oil to the lower portion of the housing, so that itwill be carried and distributed by rotation of the pinions. In order toconduct the oil to the bear-` ings, I prefer to provide wipers 1l, whichbear against the margin of the pinion and conduct the oil which theywipe therefrom to ducts 12, which lead to the bearings. Ducts 13 alsopreferably lead from the outer portion of the bearings back into thehousings, so as to return the oil thereto.

In Fig. 3 I show a modified construction in which the housingis adaptedto use with three or more pinions 7'. In this case I increase the numberof sections of which the housing is constituted, using four sections 2',3', 4', and 4*. Other modifications of the device may be made by thoseskilled in the art.

The advantages of my invention will be appreciated by those skilled inthe art. The housing is very substantial, only a few bolts are required,and it prevents the vibration of the housings and strains thereon whichhave been experienced heretofore in the use of housings for pinions oflarge size.

1. A pinion-housing and pinions Whose axes are in different horizontalplanes, said housing being made in sections divided in planes which arein parallelism with the axes of the pinions; substantially as described.

2. Apinion-housing and pinions whose axes are in different horizontalplanes, said housing being made in sections divided in planes whichsubstantially pass through the axes of the pinions; substantially asdescribed.

3. Apinion-housing and pinions whose axes are in different horizontalplanes, said housing being made in sections divided in planes which arein parallelism with the axes of the pinions, and through-bolts by whichthe sections are held together; substantially as described.

4. The combination of pinions arranged at different levels, apinion-housing formed in sections, and bearings for the pinions, saidhousing being divided into sections on planes which pass respectivelythrough the bearings, said bearings being held between adjacentsections; substantially as described.

5. A pinion-housing made in sections, with pinion-bearings held betweenadjacent sec- IOO tions, said bearings having angular portions engagingthe housing and adapted to prevent turning of the bearings;substantially as described. 1

6. A. pinion-housing made in sections, With pinion-bearings held betweenadjacent seotions, said bearings being interlooked with thehousing-sections to prevent motion of the latter on each other;substantially as dei scribed.

In testimony whereof I have hereunto set my hand.
